Product details
Overview
MAX15062DATA+T from Analog Devices is a 60V-input, 300mA synchronous step-down DC-DC converter with integrated high-side pMOS and low-side nMOS FETs, fixed 5V output (MAX15062B variant), peak-current-mode control, and selectable PFM/PWM operation. It delivers stable 5V at up to 300mA across -40°C to +125°C ambient, targeting industrial point-of-load regulation in 4–20mA loops and process control systems.
For engineers reviewing the MAX15062DATA+T datasheet, MAX15062DATA+T pinout, MAX15062DATA+T application, or MAX15062DATA+T equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and efficiency specs, and real-world alternative selection guidance for high-voltage industrial DC-DC design.
Technical Context
The MAX15062DATA+T implements a peak-current-mode architecture with internal slope compensation and a latched MODE pin that selects between constant-frequency PWM (MODE = GND) and light-load-optimized PFM (MODE unconnected). Its error amplifier compares FB/VOUT against a 0.9V internal reference, generating duty-cycle control via PWM comparator.
It integrates a 5V LDO (VCC) with 150mV dropout, hiccup-mode overcurrent protection triggered at 0.66A runaway limit, and open-drain RESET with 92% falling/95% rising thresholds and 2ms delay. Startup includes monotonic soft-start (4.1ms) and prebiased-output capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - supports wide industrial input rails including 24V, 36V, and 48V systems without external pre-regulation. |
| Output Voltage | Fixed 5.0V ±2% - regulated output for microcontrollers, sensors, and analog front-ends requiring stable 5V supply. |
| Max Output Current | 300mA - sufficient for powering multiple low-power ICs or isolated interface circuits in compact designs. |
| Switching Frequency | 465kHz to 535kHz - fixed-frequency PWM mode enables predictable EMI filtering and avoids audible noise. |
| Peak Efficiency | 92% at 24VIN/5VOUT/300mA - minimizes thermal load in sealed enclosures and extends battery life in backup-powered systems. |
| Shutdown Current | 2.2µA (typ) - enables ultra-low-power standby in always-on industrial monitoring nodes. |
| Operating Temperature | -40°C to +125°C ambient - qualified for harsh environments including motor drives, HVAC controllers, and factory automation. |
Pinout & Package
MAX15062DATA+T is housed in an 8-pin, 2mm × 2mm TDFN package with exposed thermal pad (pin 7 GND). The compact footprint supports high-density PCB layouts while enabling efficient heat dissipation through the thermal pad soldered to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power Input | Accepts 4.5V–60V input; requires local 1µF X7R ceramic bypass to GND for EMI suppression and transient response. |
| EN/UVLO (Pin 2) | Enable / Input UVLO Control | Active-high enable with programmable turn-on threshold (1.215V typ); connects to VIN for always-on or resistor divider for custom UVLO. |
| VCC (Pin 3) | Internal LDO Output | 5V regulated supply for internal circuitry; must be bypassed with ≥1µF ceramic capacitor to GND. |
| FB/VOUT (Pin 4) | Feedback Input | Direct connection to 5V output for fixed-VOUT operation; no external resistors required for MAX15062B variant. |
| MODE (Pin 5) | Control Mode Selection | GND = forced-PWM (constant frequency); unconnected = PFM (high light-load efficiency); state latched at power-up. |
| RESET (Pin 6) | Open-Drain Reset Monitor | Pulls low when VOUT falls below 92% of 5V; goes high-Z 2ms after VOUT rises above 95%; requires external pull-up. |
| GND (Pin 7) | Power & Signal Ground | Primary ground reference; connects to thermal pad and system ground plane for thermal and EMI performance. |
| LX (Pin 8) | Switch Node | Connects to inductor switch node; high-impedance during shutdown; handles ±800mA RMS current. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous MOSFET Integration | Eliminates external Schottky diode and reduces conduction losses-enables >92% peak efficiency with minimal BOM count. |
| Programmable EN/UVLO Threshold | Allows precise input-voltage turn-on control using resistor divider-supports brown-out protection in fluctuating 24V/48V industrial supplies. |
| Monotonic Soft-Start into Prebiased Output | Prevents output capacitor discharge during hot-swap or multi-rail sequencing-critical for FPGA and MCU power integrity. |
| Hiccup-Mode Overcurrent Protection | Auto-retry current limiting with 131ms timeout-protects against sustained short-circuit without thermal shutdown lockout. |
| All-Ceramic Capacitor Support | Enables ultra-compact layout with 1µF input, 1µF VCC, and 10µF output ceramics-reduces board area and eliminates tantalum reliability risks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDDARQ1 | 4.5V–65V input, 300mA, adjustable output only; requires external feedback resistors; no fixed-5V option. | Automotive AEC-Q100 qualified; lacks integrated RESET monitor and prebias startup support. | Select when automotive qualification or wider VIN margin is mandatory; avoid if fixed 5V and RESET functionality are required. |

FAQ
What output voltage does the MAX15062DATA+T deliver?
The MAX15062DATA+T is the MAX15062B variant and delivers a fixed 5.0V output with ±2% regulation over line, load, and temperature. Its FB/VOUT pin connects directly to the output-no external resistors are needed. This 5V rail powers microcontrollers, sensors, and interface ICs in industrial applications requiring stable, low-noise supply.
Does the MAX15062DATA+T support both PWM and PFM modes?
Yes, the MAX15062DATA+T supports both modes via the MODE pin: grounding MODE selects forced-PWM (constant 465–535kHz switching), while leaving MODE unconnected enables PFM for high light-load efficiency. The mode is latched at power-up and cannot be changed dynamically during operation.
What is the maximum continuous output current of the MAX15062DATA+T?
The MAX15062DATA+T delivers up to 300mA continuous output current at 5V under thermal limits defined by its 2mm × 2mm TDFN package and 162°C/W θJA. At 24VIN/5VOUT, full-load operation remains within safe junction temperature limits up to +125°C ambient when using proper PCB copper area and thermal pad soldering.
How does the RESET pin function on the MAX15062DATA+T?
The RESET pin on the MAX15062DATA+T is an open-drain output that asserts low when the regulated 5V output falls below 92% (4.6V) and releases to high-impedance 2ms after the output rises above 95% (4.75V). An external pull-up resistor is required to generate a logic-level reset signal for downstream microcontrollers or FPGAs.
Can the MAX15062DATA+T start up into a prebiased output?
Yes, the MAX15062DATA+T supports monotonic soft-start into a prebiased output in both PFM and forced-PWM modes. This prevents reverse current flow and output capacitor discharge during hot-swap or multi-rail power sequencing-essential for reliable operation with FPGAs, DSPs, and complex SoCs in industrial control systems.
